Embed at Aleppo gathers information (4)
I believe the answer is:
data
'information' is the definition.
(data are bits of information)
'embed at aleppo gathers' is the wordplay.
'gathers' says the answer is hidden in the clue (I've seen 'gathering' mean this (parts of the clue hold or gather the answer)).
'DATA' is hidden within 'embed at aleppo'.
(Other definitions for data that I've seen before include "Gathered stats" , "Facts and figures as processed by computer" , "Factual information" , "Collection of bits of information" , "Raw facts" .)
